Texas Attorney General Greg Abbott has asked the U.S. Supreme Court to step in and prevent a court-drawn interim redistricting map for congressional districts from becoming law.

Abbott’s latest filing with the court comes a day after he asked the Supreme Court to block the court-drawn interim redistricting maps for the Texas House and Senate.

Supreme Court Justice Antonin Scalia — who handles emergency petitions to the court from the 5th U.S. Circuit Court of Appeals district, which includes Texas — has given groups suing the state over the Legislature’s controversial redistricting plans until Thursday afternoon to comment on the state’s request.

If Abbott were to win his motion, it would effectively stop candidates from filing for office because they wouldn’t know what districts to run in, and could delay primary elections in Texas until May. The filing period opened on Monday and had already been delayed once to give a panel of three federal judges time to draw their interim redistricting plans.
